3. Moderate environmental conditions. Select a cool, dry area and protect your printer from direct
sunlight, excessive heat, moisture, or dust.
4. Appropriate power source. Make sure you use a grounded outlet; do not use an adapter plug. Avoid

possible.

1.6 Installing the Tractor
There are two positions for the tractor to be installed, one is push installation position (back of printer),
and the other is pull installation position (top of printer). The tractor that installed in the back of printer
is called drive tractor, and the one installed in the top of printer is called draught tractor.
Generally, you can use drive tractor when using standard tractor paper. Only in this way, can the
printer tear paper normally. If the print position requires high precision, such as printing on the paper
with forms, you are suggested using draught tractor.
1.6.1 Installing the Drive Tractor
Aim the mounting slots on both sides of tractor at the alignment pins which are at the back of printer,
press forward till it locks in place. (Shown as the following figure)
